In Montréal, all cats and dogs must be microchipped and spayed or neutered. Rabbits must also be spayed or neutered.


All cats, dogs and rabbits older than 6 months must be spayed or neutered. It’s a fast, easy and permanent way for lost pets to be found.  

For more information on microchipping, visit the Ordre des médecins vétérinaires du Québec (in French) Web site. 

Spaying or neutering

All cats, dogs and rabbits older than 6 months must be spayed or neutered.

Spaying/neutering is recommended by veterinarians. It helps curb overpopulation and limit the number of unwanted offspring. It also prevents a great many health and behavioural issues, such as scent marking and running away. To learn more, visit the SPCA Web site.


If spaying/neutering or microchipping is contraindicated for your pet, you are required to provide us with a note from your veterinarian.

Spaying/neutering is not required for breeding cats and dogs. You must provide proof that your pet is registered as a breeding animal with a recognized breed association.
